GraphQL error: Cannot query field 'user' on type 'AuthenticateUserPayload'

[toyeebgodo]

@nikolasburk I got the error below while I was testing things out during the "More Mutations and Updating the Store" chapter. After my votes feature worked as implemented, I decided to log out and log in again at which point I got this error. I am unable to log in with either of the two test accounts that I created and have been using since the "Authentication" chapter. Please help.

In Login.js define your AUTHENTICATE_USER_MUTATION as this:

const AUTHENTICATE_USER_MUTATION = gql`
    mutation AuthenticationUserMutation($email: String!, $password: String!){
        authenticateUser(email: $email, password: $password){
            token
            id
        }
    }
`

This works if in your backend you have provided mutation as:
createUser(name: String!, email: String!, password: String!): User

Addressed here #14 & provided here
